. specification.

The object of this invention is to provide a cheap and convenient device for painters use that can be readily adjusted and conveniently .operated to expel plastic colors from the cans in which they are put up and sold.

The invention consists in so mounting a piston in arms projecting from a plate above a similarlyprojecting shelf that it may be forced down to expel plastic color from a can placed upon said shelf by a ratchet acting upon a toothed piston-rod, which rod can be readily detached from its actuating-ratchet, so as to permit thepiston to be "rapidly withdrawn by hand from the empty can, and se cured in its elevated position until a filled can is replaced preparatory to another operation.

It consists, also, of a peculiar construction and airangement of slide, pawl, and actuatinglcver to operate the piston. i

In the accompanying drawing, which is a perspective view of my improved machine, A is a plate, which has a shelf, B, two arms, 0 and D, and a stud-pin, E, projecting at right angles from it. These parts I prefer to make of cast-iron, molded in a single piece. The outer ends of the arms 0 and D are perforated to receive and guide the toothed bar F, which carries at its lower end the piston Gr. (Shown in dotted line within the can H, which it closely fits.)

I is a slide fitted over the piston-rod F, between the arms (1 and D. This slide has journaled in lugs projecting from it a weighted pawl, J, which engages the teeth upon bar F. It has also projectingf'rom its rear side a pin, which enters a longitudinal slot in the actuating-lever K, which lever has its fulcrrim upon stud-pin E.

The lower arm, D, has a set-screw, S, tapped through its end, for the purpose of retaining the piston G in any desired position.

L represents a pillar, or part of a wall, to which the machine is secured by screws passing through plate A.

the piston and expel the paint, as represented in the drawing.

If sufficient color is not expelled at one stroke. the operation may be continued until the entire contents of the can are expelled.

When the required amount has been withdrawn, the set-screw is tightened and the lower cap replaced. The paint will thus be kept from drying when not in use. and no waste occur from careless handling of the machine, as the setscrew rigidly holds the piston.

After the contents of the can have been ex- 7 polled, the pawl J is disengaged from the teeth of the bar F. The slide I will then drop down upon the lower arm, D, which will hold the pawl disengaged. Now, by taking hold of the bar F, the piston can be rapidly withdrawn from the can and the set-screwtightened, thus holding the piston in its elevated position until the empty can is removed and replaced by a filled one.

I claim- 1. The bracket substantially as hereinbefore described, in combination with the piston, the toothed piston-rod, the lever for moving said rod in one direction, and the set-screw for securing said rod at any point in its range of motion.

2. The combination, with a piston having a toothed piston-rod suitably mounted, as described, of the slotted lever K,pivote.d upon stud E, the pawl J, and slide I, said slide carrying a pin to enter the slot in the lever, sub stantially as specified.
